Human breath contains hundreds of VOCs, many at trace concentration levels. Characterization of compounds in human breath can be used for non-invasive diagnosis of diseases, assessment of physiological functions, therapy control, and pharmacokinetic studies. Analysis demands ultra-low detection limits, broad dynamic range, and fast time response. With unmatched sensitivity and mass …
The rapid detection of COVID-19-specific breath VOCs would be a great step forward for diagnostic purposes and a spectrum of VOCs could be used for monitoring disease progression or response to conventional or investigational drugs. Since therapies for COVID-19 are experimental at this stage, directly monitoring the effect of a therapeutic drug speeds up the development of an efficient ...

· Der Gas-Detektor SPS30 kommt im Q4 2018 auf den Markt. CO2 ist neben den VOC ein maßgeblicher Indikator für die Luftqualität. Laut DIN EN 13779 ist die Raumluft bis zu einem CO 2 -Gehalt von 800ppm gut, ab Werten von 1400 ppm gilt die Luftqualität als niedrig.
· Rapid detection of volatile organic compounds (VOCs) is highly demanded, as many VOCs can cause both acute and chronic health effects , , also induce reduction of agricultural yield and deterioration of outdoor air quality . Portable VOC detection devices with high sensitivity and selectivity are required in many fields to replace bulky and expensive analytical apparatus like gas …
· VOCs are volatile chemical compounds. They are defined as so because they easily evaporate and release molecules into the atmosphere. By using gas detection equipment, exposure to VOCs can be monitored. ION Science produces gas detection equipment for monitoring exposure to toxic levels of VOCs. At ...
The Inert Flow path includes GC components from injector to detector resulting in a reliable inertness level that prevents cross-contamination enabling very accurate quantification of VOCs. Agilent's 7697A Headspace Sampler, when coupled with the market leading 7890 GC and 5977B Mass Spectrometer, delivers accurate and reliable analysis of VOCs in water.

· Understanding Both the PID Detector, the Application and the Limitations. PID Detectors are commonly used to monitor VOC’s (Volatile Organic Compounds). Many gases and vapours fall under the VOC banner and IGD’s PID’s can monitor for over 300 Gas species. This makes a PID an ideal first responder for VOC leaks even though the PID cannot directly determine the gas type detected. – See ...

· To detect specific VOCs of low concentrations from exhaled breath, and to enhance the accuracy of early diagnosis, many breath collection and analysis approaches have been developed. This paper will summarize and critically review the exhaled-breath VOC-related sampling, collection, detection, and analytical methods, especially the recent development in VOC sensors. VOC sensors …
Volatile Organic Compounds (VOCs) emanate from a broad range of sources in industrial and general indoor air quality (IAQ) applications. GrayWolf offers five different plug-and-play Photo Ionization Detector (PID) sensors to choose from; with ranges optimized for your specific application. The DirectSense II-3 probe includes your choice of any of those PIDs, along with relative humidity and ...
A photoionization detector can analyze a wide range of chemicals, including aromatic hydrocarbons, but excluding low molecular weight hydrocarbons. PID works by using ultraviolet light to break down airborne VOCs into either positive or negative ions. Once broken down, the detector can then measure or detect the charge of the ionized gas. It should be mentioned that PID only temporarily ...

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
